So if it pushed terrain around without lowering, then is depth only referring the amount of raising around the point of force? So it's making the rut by building up around the line vs. digging into and displacing?
That being the case, I think allowing for lowering would be a good addition.
As to multiple layers, would it be possible to simply add a setting for regressive-like deformation? So on a scale from 0 to 100, 0 would 100% of erode every time force is applied, 1 would be 1% less for each successive force (each time someone takes the same line), 5 would be 5% less, etc.
